      Input: matrix-keymap - wire up device tree support · b45c8f35
      Dmitry Torokhov 提交于
      When platform keymap is not supplied to matrix_keypad_build_keymap()
      and device tree support is enabled, try locating specified property
      and load keymap from it. If property name is not defined, try using
      "linux,keymap".

      Subject: [PATCH] Input: omap-keypad: dynamically handle register offsets
      
      Keypad controller register offsets are different for omap4
      and omap5. Handle these offsets through static mapping and
      assign these mappings during run time.
      
      Tested on omap4430 sdp with 3.4-rc3.
      Tested on omap5430evm with 3.1-custom kernel.

      Input: ALPS - add semi-MT support for v4 protocol · 3b7e09fa
      George Pantalos 提交于
      This patch adds semi-MT support for ALPS v4 protocol touchpads.
      It is based on the work by Seth Forshee for ALPS v3 and v4 protocol
      support. Three packets are required to assemble and process the MT
      data. ST events are reported at once to avoid latency. If there
      were two contacts or more, report MT data instead of ST events.
      
      Thanks to Seth Forshee for providing most of the code, guidance
      and insight for producing this patch.

      This driver adds support for the Synaptics NavPoint touchpad connected
      to a PXA27x SSP port in SPI slave mode. The device emulates a mouse;
      a tap or tap-and-a-half drag gesture emulates the left mouse button.
      For example, use the xf86-input-evdev driver for an X pointing device.
